Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452064, here are decompositions:

3 + 31452061 = 31452064
23 + 31452041 = 31452064
71 + 31451993 = 31452064
227 + 31451837 = 31452064
257 + 31451807 = 31452064
263 + 31451801 = 31452064
311 + 31451753 = 31452064
353 + 31451711 = 31452064

Showing the first eight; more decompositions exist.
